Input analog voltage to FB terminal
I
This method is without repeating IC ON/OFF, and no need to consider holding rash current.

Input PWM signal with filtering to FB terminal
I
PWM signal can be regard as analog voltage after filtering.
This method is without repeating IC ON/OFF, and no need to consider holding rash current.

F
can be adjusted with analog voltage input to FB terminal.
can be adjusted with filtering PWM signal using RC filter indicated in recommended circuit, because the
LED current value goes over 100% of the current set with RSENS, if the input analog voltage is
between 0 V to 300 mV (typ.).
